A gentle pour produces three finger of rocky, dark tan bubble that settle to a thin cap leaving some lacing on the glass. The beer is almost opaque with light just penetrating the thin edge revealing a very deep garnet.

The first thing you smell is moderately sour/acidic and dark malt with some light coffee and cocoa aromas. Some esters of plums come through. After my glass warmed a light goaty and earthy funk from the sour developed.

A big mouth watering, intense sour hits you on the first sip, far more than the nose suggests. The sourness has free range of the show here with just a trace of malt sweetness to balance it. There also some dark malts flavors with a touch of cocoa in the back; it takes a while but roasted and burnt grain flavors come through that remind me a nice dry American stout. The sourness and roasted grain flavors continue into a long dry finish.

This is a medium body with a lively, light carbonation.

Mardugada Obscura is an intensely sour beer with notes of dry stout. It's defiantly not for everyone but I think it's pretty amazing beer.

This is where other beers come to be decimated and pronounced simpleton swills of bulging Amerigo. In fact this is the war of the worlds brew that comes out of the ground and goes GEEE GLEEENNNNK and then starts zapping people and turns them to quivering dust piles. I saw a man carrying a case of Bud Light walking in 95 degree heat as I was driving towards the Jolly Pumpkin headquarters today and I cursed his existence and made inside my brain those exact same GLLLEEEKEKKEKE sounds and he was gone from the face of the planet beer. I pulled in and mooched three samples with this being the last and bought three bottles with this being the first tasted. What you have here is a copper bodice and the queen is being fed chinked off pieces of the Sphinx and grape wine and the blood of three virgins. Her hair is flaming and her mouth is cursed with the comprachico's everpresent and everlasting grin-smirk-smile. You have a porter with God's little magic wand in it making a mushroom cloud of exploding suds that implodes from the center down in a burst of purple froth. You have to harness this head because it whips around and screams and threatens to put your life in the dustbowl if you don't dive right in and be overcome by excellence.

Pours a deep black with a two finger head of tan foam that sticks on top. Some lacing as well. Head stays around awhile, looking good. Aromas of chocolate and roastiness. A fruity aroma with some funky sourness and an oak undertone. Slightly spicy and quite interesting!

First sip brings a mild roasty maltiness along with some chocolate and light fruit tones. Flows down with a touch of smokiness. Sour tones come through and they can be quite strong. Earthy yeastiness brings in a spicy aspect. Oak comes through on the finish with some herbal hop bitterness. Sour lingers on after each sip.

This is a light bodied stout here for sure. Easy drinking and quite interesting. Not sure I could drink all that much of it myself, but it's a good bottle to share with friends or family. Another JP brew worth looking out for!

A - Pours deep brown/black with three fingers of brown head. By far the darkest beer I've seen from JP. Head has great retention and leaves quite a bit of lacing.

S - Tart and funky up front, with some green apple and tart cherry. Then the stout elements become apparent, with roasted malt, bitter chocolate and a bit of milk chocolate. Nice.

T - At first it tastes like a lot of other JP beers, with a funky sourness, including some apple. But midway through, the chocolate and roasted malts really identify this as a stout. There is some sourness throughout, but it mostly hits up front. The finish is roasty and somewhat dry like bitter chocolate. I think this works well.

M - Medium mouthfeel that feels lighter initially and a bit heavier on the finish. Finish is several types of dry: a bit earthy/funky, a bit roasty, and a bit bitter.

O - Definitely an interesting brew from Jolly Pumpkin. I think it works well and is pretty tasty, but it doesn't make me eager to have more sour stouts, either.

750 ml bottle. Pours a dark brown with a large fluffy brown head that retains well and laces the glass.

The aroma is grainy lactic chocolate with some spicy hops and a little band-aid.

The flavor is roasted malts with a vinous sour fruitiness. The finish is roasted bitterness. The mouthfeel is medium and creamy.

Overall, it's kind of jarring to have a sour stout. It seems to balance out and blend as it warms and I drink more. I'm not quite sure how much I like it, but it's a fun beer and I'd definitely have it again.

The beer pours a dark brown color with a khaki head. The aroma is brown sugar, alcohol and dark cherries. The flavor is pretty tart with some sour cherries and a lot of notes from the oak aging. Medium mouthfeel and medium carbonation. A very nice slightly sour stout.

Pours jet black with a huge, cascading brown head. Rich aroma of burnt coffee, chocolate, bourbon, leather, and sour yeast. Once this warmed, it was very good. Tons of roasted malt, with coffee, chocolate, currants, smoke, and oak. I could have done without the sour yeast. It drowns out whatever hop bittenress they intended. It doesn't ruin the beer (like Avery 15) but it also doesn't make it better. All in all, this is still a very good stout.

L: It pours a dark coffee brown with a rich 1” tan foam collar that hugs the glass.
S: The aromas are fruit, wild yeast, and perhaps a touch of rotten fruit or barnyard funk in the aroma and a suggestion of port.
T: A creamy start immediately gives way to tartness that expands through the mouth. Fruit, spice, faint caramel, and complex layers of lemony, vinegary tartness. Soft roast flavors. Nothing burnt or harsh. Faint bitterness on the finish.
F: Has a very fine and soft texture, medium carbonation and body.
O: A very unique imperial stout that high lights wild yeast in a very nice way.

Dark black and thick appearance. Tall, growing brown head that lasts. Regular, lined lacing down the glass. A gorgeous stout!

The aroma on this beer changes as it warms perhaps more than any other beer I've had. It begins slightly roasty and bready, evolving in to a tart, tangy, biting sour mixed with sweet fruit--like cherries or raspberries.

As with the nose, this beer really changes as it warms. It begins slightly roasty and bready, and at near room temperature, it's a biting sour mixed with some sweet fruit. There isn't a lot of typical-"stout" flavors left over. It's missing a depth, balance, and complexity I was hoping for. Tasty, and certainly unique.

Medium bodied. I was hoping for a more full, luscious mouthfeel.

An interesting and unique sour stout. For my tastes, I would have preferred a touch less of the acidic sour notes because the typical stout flavors got left in the dust, leaving this beer relatively one-note: sour.
